' Application filed July 30, 1913. Serial No. 782,084.

consisting ofa plurality of independently pivoted superposed decks, such as form the subject-matter of Letters Patent Nos. 1,007,074 and 1,007,075, dated October 31, 1911.. As stated. in said patents, the material to be treated, as slime, is caused to flow slowly and in thin streams from'end to end of said decks, when in an inclined position. The decks are then inclined in the opposite direction and the values deposited onv their; surfaces washed oiL when the decks are returned to feed position and the de scribed operations repeated. a The invention described herein has for its object to provide for the successive operationof a plurality of such units by a common uniformly o erated member and to effeet the describemovements of 'the decks of "each unit in such manner as to Insure the proper duration of the {feed-mg and washing periods. f

The invention is hereinafter more fully described and claimed. H

In the accompanying drawings forming a part of this specification, Figure 1 1s a side elevation, of a concentrating unit In "combination with an element or .section of the battery operating mechanism; Figs. 2 and tare edge and sideelevations respec- 'tively of an element of the common operating-mechanism; Fig. 3 is a detail view of a portion of the mechanism shown in Figs. 9 45 ch ld, and Fig. 5 is a view similar to Fig. 1, illustrating a arrangement of the decks and the operating mechanism, and Fig. 6 is a diagrammatic {View illustrating a battery of concentrating In the practice, of my invention, each unit of the battery is. constructedsubstantmlly es-descri ed and. shown in the patents. re-

As fully disclosed in said patents provision is made for automatically controlling by the decks as they move from one position to the other the flo of material and water onto the geeks in accordance with the position ofthe While not necessary, it is preferred that the decks should have their pivotal points so located that the decks have a constant bias to move from washing to feed position and hence the improvement is shown and described in connection with decks so sup-' ported, but as regards the broad statements or claims, the invention is not limited to such construction. T

As will be seen by reference to Fig. 6, the concentrating units A, B, C, D, are preferablyarranged side by side, so that the slime and washing water can be supplied to the decks of the several units by troughs 2. The tailings are dischargedinto alaunder 4 and the values into a launder (not shown) Patented Mar. 3, 1914:.

below the slime launder 2. The deck oper- 'ating and controlling units are preferably operated by a common shaft 5 extending the length of the battery and driven by any suitable means as a motor 6. 1 As clearly shown in Fig. 1, the several decks are flexibly tied together so as to move in unison by straps 7, and turn buckles 8 have their respective ends loosely connected to the lowest deck and the ends of a walkin beam 9. This beam is secured mid way oi its length to a shaft 10, which is mounted in suitable. bearingswith its'axis coincident with a vertical plane passing through the pivotal axes of the decks. The walking beam y ative relation to. the cam 12 on the driven shaft 5. The lower end of the arm 11 is provided with a part or member 13 (preferably made in the form of a roller) laterally movable into and out of the plane of rotation of the. cam. As shown in Figs. 2 and 4: thisroller is provided with a short shaft 114 loosely mounted in. bearings on the end arm 11., and is adapted to be shift-ed. into the an arm 11 extending'down into oper-,

is oscillated to shift the decks v of the] and out ct such plane by a rib 16 eatending an angle across the face of the cam.

A suitable lock is provided for holding the roller out of alinement with the cam during the time slime is being fed onto the decks.

A convenient form of lock consists of a fin- 17 carried by a slide 18 and :ted be forced by the. spring 19 1nto peripheral groove 20 in the shaft 14; when the latter has been shifted'by the rib 16. The slide is A mounted in suitablebearings on the arm 11 and is provided with a shoe 21 which is engaged to raise the .slide and unlock 14 byan Figs. 1, 2 and arm 22 on the'counter-shaft This counter-shaft is driven through a Worm gearing 2 1 by the main shaft 5, such gearing being so designed as to impart one complete rota .tion'to the counter-shaft carrying the unlocking arm 22 for any desired number of rotationsof the shaft 5 and cam 12. As'the decks are in feed position -while vthe roller 13 is out of alinement With the cam,' the number of rotations of the shaft-5 to one rotation of the unlocking arm, Will be dependent upon the number of revolutions per 'minuteof the shaft and the desired duration of feed. In lieu of arranging the power shaft 5 and the deck shifting mechanismsin line Vertically with the pivotal axes of the decks asshown in Fig. 1, they maybe arranged at one side of the plane of such axesas shown in Fig. 5.

.In describing the operation of my inn provement it will be supposed that the cam is moving in the direction of the arrows a, i 3, and-theslime feeding period is terminating. As the unlocking arm 22 continues its movement in the direction of the arrow 2), it Willraise the slide 18 interlocking the shaft 14:, which will then be,

shifted by springs 15 moving the roller 13 into the plane of rotation of the cam. The

advancing shoulder 0 on the cam will engage the deck shifting arm 11 and push it i to the left in Fig. 1 and thereby shift the decks from feed to washing position. While the portion ofthe cam between the shoulder a and the point (Z is in engagement with the arnrll, the decks will be held in Washing position. V hen the point (Z reaches the arm, the decks which as stated have a bias to move from washing tofeed position, will begin their return increment. The portion of the cam between point (Z and the rib 16 is so constructed that the rate or" the return movement 'Wili progressively increase until the roller is shifted laterally by the rib 15 when the decks will be .frce to complete the return to feed position. At the beginning of the return movement the Washing water is cut oil as shown and described inihe patents referred to, and opportunity is afford- -ed while the portion of thecam between.

As the slime to be d richness from time to time and as the dura tion of the feeding period is dependent on the richness of the slim the 'if cd period. can be lengthened or shortened by changing the relative rate of rotation of shafts 5 and 23. And in lieu of feeding an the units of battery from a common launder, they may be independently supplied, and in case may vary in the slime fed to some of the units is richer than that fed to others, the feed period of such unitcan be shortened Without afiecting the operation of the other units.
